title: Futcher lines: a case report in pregnancy and literature review.
abstract: Pigmentary demarcation lines are common, especially in individuals with darker skin types. Type B pigmentary demarcation lines (Futcher lines) involve the posterior lower extremities and can be associated with pregnancy, often with spontaneous resolution after delivery. The pathogenesis of pigmentary demarcation lines remains unknown; however, neurogenic inflammation and/or mosaicism are thought to play a role in their development. We report a case of type B pigmentary demarcation lines in pregnancy and provide a review of the literature.
